A dark side to your cellphone?

We love our digital gadgets -- "magic" devices that define cool and promise to remake our lives for the better. But there is growing evidence of a dark side to the techno-magic. Your cellphone, and any other wireless device that depends on electromagnetic (EM) microwave radiation to function, may be hazardous to your health.

Most of the bad news comes from major labs and research institutions in Europe . What they're reporting is that using cellphones and Wi-Fi transmitters -- which operate using similar frequencies -- can have biological effects on the brain and body.

The scientific debate remains heated and far from resolved, as the Health section in The Times reported last week. But the research to date suggests a number of chilling possibilities as to what EM radiation may be doing to us.

For example, in 2008, neuroscientists at Swinburne University of Technology in Australia strapped Nokia phones to subjects' heads, then turned the phones on and off. On -- the brain's alpha waves spiked. Off -- the brain settled. The researchers speculated that the effect was the result of the brain "concentrating to overcome the electrical interference in brain circuits caused by the pulsed microwave radiation."

Swedish neuro-oncologist Leif Salford, chairman of the department of neurosurgery at Lund University, has found that cellphone radiation kills brain cells in rats, especially those cells associated with memory and learning. The damage occurred after an exposure of just two hours. In duplicating earlier research, Salford also found that cellphone microwaves produce holes in the barrier between the circulatory system and the brain in rats. One potential outcome, according to Salford , is dementia.

Meanwhile, Austrian researchers reported in 2004 that cellphone radiation can induce double-strand breaks in DNA , one of the undisputed causes of cancer.

So why isn't this a bigger issue in the U.S. ? Partly because there are countervailing studies and other scientists telling us not to be worried, that the risks are low or that we just don't know enough to say that the risks are real.

Consider the biggest study being done on the question of whether cellphones cause cancers of the brain, mouth and ear -- the 13-country Interphone study conducted under the auspices of the International Agency for Research on Cancer in France. The study's epidemiologists have looked at cancer patients and worked backward to establish cellphone habits.

The study, alas, has been fraught with controversy. The multinational researchers -- U.S. scientists conspicuously not among them -- have fallen into warring camps, and the full study has not been released.

However, pieces of the study have been made public. One Interphone study, for example, found that after a decade of cellphone use, the chance of getting a brain tumor goes up as much as 40% for adults. Another Interphone study reported a nearly 300% increased risk of acoustic neuroma, a tumor of the acoustic nerve. But still other Interphone researchers say their data show no increase in brain tumors -- or any tumor -- caused by cellphone use.

The cellphone industry lobby, CTIA -- the Wireless Assn., recently said in a statement that "peer-reviewed scientific evidence has overwhelmingly indicated that wireless devices do not pose a public health risk." Meanwhile, watchdog groups keep it vague. "The available science," says the Food and Drug Administration, "does not allow us to conclude that mobile phones are absolutely safe, or that they are unsafe."

So whom to believe, and what to do?

First, consider research done by Henry Lai, a biologist at the University of Washington : Only 25% of studies funded by the wireless industry show some type of biological effect from microwave radiation. Independently funded studies, however, are far more damning: 75% of those studies -- free of industry influence -- show a bioeffect. Some 30% of funding for the Interphone research was provided by industry, which critics say has resulted in a favorable skewing of some Interphone data.

Obviously, we need to demand more independent research into microwave radiation. In the meantime, we should also treat cellphones and other wireless gadgets with less adoration and more suspicion, and as individuals we may want to follow the lead of many nations and regulate the way we use them for ourselves.

For example, Belgium , France , Finland , Germany , Russia and Israel have publicly discouraged use of cellphones by children. (Independent research in Sweden last year concluded there was an astonishing 420% increased chance of getting brain cancer for cellphone users who were teenagers or younger when they first started using their phones.) France has gone so far as to issue a generalized national cellphone health warning, banned cellphones in elementary schools and considered outlawing marketing the phones to children.

The personal equivalent? For starters, don't get rid of your land line. Buy a hands-free device; keep your cellphone away from your head, face and neck. Don't carry it in your pocket for hours on end(there's some evidence cellphones aren't good for your sperm count).

Salford , the neuro-oncologist, has called the unregulated use of cellphones by 4.5 billion people worldwide "the largest human biological experiment ever." It's only common sense to do what you can to take yourself out of the guinea pig pool.

Christopher Ketcham is the author of "Warning: Your Cell Phone May Be Hazardous to Your Health" in February's GQ.

THE NICEGUIDELINES BLOG VERSUS THE NICEGUIDELINES

These are NOT the NICEGuidelines. This is "The NICEGUIDELINES BLOG." What are the differences:

The NICE Guidelines are biased publications based on the GOBSART (Good Old Boys Sitting Around a Table) approach.

This Blog however is not only evidence based but also uses critical reading to judge papers and articles. I also use common sense and listen to others. And finally I read both psychiatric and medical evidence and opinions from around the world to come to a conclusion.

I’m not sponsored by anybody or paid by whatever company as seems to be the norm with many psycho people who publish the same article almost on a weekly base.

So if you value an opinion, formed as a result of participating in many ME activities, for example being bed bound for years, you have come to the right BLOG. All these activities have allowed me to form an opinion as a Doctor and as a Patient. And that is important as the voice of the latter is discarded by many including NICE.

If you don’t read this blog, you will miss out on “accredited” medical education. If you do read it, you may actually become a doctor who doesn’t stop thinking or forgets to ask critical questions. Many good things, including satisfied patients are at your command.

So, if you arrived here for the straightforward GOBSART approach, I will disappoint you. If you are interested in forming your own opinion about ME, and other interesting things, read on!

About Dr. Speedy.

I am a Family Physician or GP as it is called in Australia or the UK. I am also an ME patient unfortunately. Bedbound that is. So at the moment I’m in private practice so to speak. I’ve got only one patient, ME, or is it me?

I graduated as a doctor a long time ago, and I am the founder and editor of The NICEGUIDELINES BLOG, an internet based ME BLOG that is devoted to critical reading and cheering you or ME up.

I have the following conflict of interest: I would like to get better and see that the wasting of public money on CBT (talk therapy for a neurological disease, really helpful) and other silly therapies for ME stops, and will be used in better ways.

My goal has always been to help, and if possible, cure patients. With this disease you will soon find out that many psychiatrists and psychologists are only in it to make money and get their name in the spotlight. And what happens to and with the patients is irrelevant.

I stand to benefit both mentally, physically and also financially if this silliness would stop, and I would get my health back, and I can go back to work and have a normal life again. Please evaluate my postings with this in mind! And remember, there are also (lots of) psychiatrists and psychologists who haven’t switched their brain off.
